So i have this 50mW green laser pointer that is confusing me. I have read somewhere that you need at least a 100mW to light matches and to sting skin. My 50mW stings my skin the second i put it on my skin, but it can not light a match. It can pop balloons, cut electrical tape (easily), cut plastic trash bags, and many more fun things. What is going on?
